This puts it in the class of MCUs that can handle real-time control loops, motor FOC, and DSP filter chains without a separate DSP coprocessor. For applications that stream sensor data or run a TCP/IP stack with a GUI, this memory budget often eliminates the need for external parallel SRAM or serial flash. ## Connectivity and analog front-end for industrial gateways This makes the STM32H743XIH6 a natural fit for a programmable logic controller or an industrial communication gateway that bridges fieldbus and Ethernet. On the analog side, 36 channels of 16-bit ADC and two 12-bit DAC channels handle multi-channel sensor acquisition and analog output generation. The 168 GPIOs in the 265-ball TFBGA package give enough headroom for parallel address/data buses, external memory interfaces, and custom peripheral muxing. The base product number is STM32H743 — this is the high-performance member of the STM32H7 family. Operating temperature range is -40°C to 85°C (TA), suitable for factory-floor, outdoor enclosure, and HVAC deployments.","metaTitle":"STM32H743XIH6 STM32H7 MCU, 480MHz Cortex-M7, 2MB Flash","metaDescription":"STMicroelectronics STM32H743XIH6 ARM Cortex-M7 MCU, 480 MHz, 2 MB flash, 1 MB RAM, 168 I/O, 265-TFBGA.
